SPECIFICATION forming part of Letters Patent No. 451,130, dated April 28, 1891.

Application filed February 24, 1890. Serial No. 341,532. (No model.)

T0 all wiz-0m! t may concern:

Be it known `that I, JOHN MOREHEAD, a citizen of the United States, residing at Detroit, county of iVayne, State of Michigan, have invented a certain new and useful Improvement in Beer-Pumps; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specication.

My invention relates to certain new and useful improvements in beer-pumps; and it consists of the combinations of devices and appliances hereinafter specified and claimed, and more fully illustrated in the accompanying` drawings, in which- Figure 1 is a vertical cross-section embodying my invention, showing parts in elevation; and Fig. 2 is a side elevation.

The purpose of my invention is to provide a beer-pump which will be automatic in its working as Well as simple and efficient in its operation. To this end I employ a tilting receiving-chamber A, axially supported at one side its center of gravity, as upon pipes B2B', journaled upon a suitable support O. The pipes B and B communicate separately with the interior of the chamber A, as shown at b and b. The pipe B is connected With an interior pipe b2, rising upward within the chamber above the Water entering thereinte. Between the communications b and b may be located a blank or closed wall b3. The pipe B denotes an inlet water-supply pipe, which may communicate With the city watersupply system, so that the Water shall be admitted into the chamber under pressure. I prefer to provide said inlet-pipe with arcgulating-valve B2 to control the pressureof the water-supply. Said pipe B is also provided with a valve B3, of any suitable construction, arranged to open when the chamber is in normal condition and to close when the chamber tilts to relieve itself of the water entering thereinto.

A simple way of accomplishing the opening and closing of said valve is to provide the valve-stem with a lever-arm C', preferably dition.

weighted, as shown at C2, to trip the lever as the rear of the chamber descends. I provide, also, a stationary arm D, which may be conveniently secured upon the supporting-base O, the said arm being so located that when the chamber is in normal position the arm C will strike upon the arm D, raising the outer extremity of the lever-arm and opening the valve. Vhen the chamber tilts, the gate in the valve descends to its lowest point, and as the chamber continues to tilt the lever C is lifted from the arm D and the Weight holds down the outer end of said lever, thus keeping the gate in the valve closed. The pipe B is also provided with any suitable checkvalve B4, adapted to open by pressure from the chamber and to close when the' pressure from the chamber is relieved, and a reacting pressure is exerted thereupon in the opposite direction, as from the beer-keg. Said pipe B', communicating with the interior pipe b2, is thus an air-exit pipe controlled by the valve B4. It may be provided With any suitable tip for connecting a hose-pipe E thereto, said hose-pipe leading to the beer-keg F in the customary manner. The chamber A is, moreover, provided with an inlet air-valve G,con nected therewith in any suitable Way, said valve being arranged to close when the chambei` is in normal condition to prevent the escape of air therethrough and to open when the chamber is tilted to permit the entrance of air thereinto to assist in expelling the Water therefrom and to fill the chamber With air when the same is restored to normal condition. To this end said valve G may be provided with a lever-arm G', and a stationary tripping-arm H be so'located that the arm G will strike thereupon when the chamber tilts to open the valve, the arm G being provided with a Weight G2 or analogous device to close the valve when the chamber is in normal'con- At the lower rear end of the chamber I also locate a relief-valve J, provided with a stem j, projecting beneath an outlet-pipe J', in which the valve may be located, to open when the chamber tilts and arranged to close when the chamber is restored to normal position. The discharge-pipe J', I prefer to bend rearwardly, the Water being discharged there- IOO from into a pan or other suitable receptacle K, from which the water can be conducted into the Waste-pipe K. 4

To restore the chamber to a normal condition, I provide it with a Weighted arm A.

The operation of the device is as follows: Suppose the chamber to be closed and Water to be just admitted thereinto through the pipe B. At this instant the chamber is illed with air. The valves G and J prevent the escape of air from the one and Water from the other. In consequence of the pressure of the Water-supply it is evident the air in the chamber must be expelled, as 4the Watersupply ills the chamber through the pipes b2 and B into the beer-lieg- W'hen the Weight of Water in the chamber so increases as to overcome the gravity of the Weighted arm A', the chamber tilts, opening the valves .I and G, as above described, when the Water is discharged from the chamber and the air is again admitted thereinto. It is obvious that When the Valve G is opened pressure is relieved from the Valve Bl from the direction tilting receiving-chamber axially supported at one side the center ot gravity, of an inlet Water-supply pipe provided With a pressureregulating valve B2 and a valve B3 to control the admission of Water to said chamber, an air-exit pipe provided with a controllingva-lve B4, an air-inlet valve G to control the admission ot air to the chamber, and a Waterdischarge valve J to control the discharge of Water therefrom, the valves B3 and B4 arranged to open when the chamber is in normal position, and the valves G and J arranged to open when the chamber is in a tilted position, and vice versa, substantially as set forth.

:2. In a beer-pump, the combination, with the tilting chamber, Water inlet and outlet ports communicating With said tilting chamber, and an air-pipe led into the chamber and projecting with its end above the Water-level therein, of a cut-off valve B3, a weighted lever O', connected therewith at one end, and a post for supporting the opposite end to hold said valve open in normal position,and Whereby When the said chamber is tilted the Weighted lever Will close said valve, substantially as set forth.

In testimony whereof I sign this specifica- 4 tion in the presence of two Witnesses.
